ABSTRACT:
A distributed digital switching system is provided that includes a plurality of service controllers (20) which are interconnected to each other through a network (10). A network arbitrator is provided that controls the flow of traffic on the network (10). Each of the service controllers (20) is operable to provide a switching configuration between inbound data to the service controller (20) and network terminations associated with each of the service controllers (20). A processor (150) on each of the service controllers (20) controls the operations thereof with the voice information stored in a memory (208) which can be configured with a circuit (204). Each of the service controllers (20) has associated therewith a conference circuit for defining and creating a conference that can access all inbound data and provide interconnections therebetween and output this on a single outbound conference channel. There can be multiple conferences created at each service controller (20). Each of the conferences on the network can be accessed with a single associated conference address, such that only one address need be defined on the network for a given conference.
